edge_color (color or array of colors (default=’k’)) – Edge color. Can be a single color or a sequence of colors with the same
length as edgelist. Color can be string, or rgb (or rgba) tuple of
floats from 0-1. If numeric values are specified they will be
mapped to colors using the edge_cmap and edge_vmin,edge_vmax parameters.

arrows (bool, optional (default=True)) – For directed graphs, if True draw arrowheads.
Note: Arrows will be the same color as edges.

arrowstyle (str, optional (default=’-|>’)) – For directed graphs, choose the style of the arrow heads.
See :py:class: matplotlib.patches.ArrowStyle for more
options.

arrowsize (int, optional (default=10)) – For directed graphs, choose the size of the arrow head head’s length and
width. See :py:class: matplotlib.patches.FancyArrowPatch for attribute
mutation_scale for more info.

Depending whether the drawing includes arrows or not.

Notes

For directed graphs, arrows are drawn at the head end. Arrows can be
turned off with keyword arrows=False. Be sure to include node_size as a
keyword argument; arrows are drawn considering the size of nodes.
